Thioglycoluril as a novel hydrogen-bonding organocata- lyst, combined with NBS, in MeOH provided rapid and efficient α-monobromination of 1,3-dicarbonyl compounds in excellent yields at room temperature. A bifunctional catalytic mechanism was proposed from these results.
硫代甘脲作为一种新型氢键有机催化剂,与 NBS 结合,在 MeOH 中提供了快速有效的 1,3-二羰基化合物的 α-单溴化,在室温下产率极好。根据这些结果提出了双功能催化机制。
